Post-Installation Care
New Sod Watering Schedule — First 30 Days
The first 30 days after installation determine whether your sod survives or dies. Watering is the single most critical factor. Under-watering kills sod within days. Follow this schedule carefully.
Critical: Do Not Skip Watering
New sod can die within 24-48 hours of drying out during the first week. If you cannot commit to the watering schedule below, consider installing a temporary irrigation timer or hiring someone to water during the first two weeks.
Days 1-3
Frequency
3-4 times per day
Duration
5-10 minutes each
Target Depth
Keep soil moist 1 inch deep
Sod must not dry out at all. Edges and corners dry fastest. Water early morning, late morning, early afternoon, late afternoon.
Days 4-7
Frequency
2-3 times per day
Duration
10-15 minutes each
Target Depth
Soil moist to 2 inches
Reduce frequency slightly but increase duration. Gently tug a corner — if it lifts easily, roots haven't taken hold yet.
Week 2
Frequency
Once or twice daily
Duration
15-20 minutes
Target Depth
Soil moist to 3 inches
Roots should start anchoring. Reduce to once daily if sod feels firmly attached when tugged.
Week 3
Frequency
Once daily or every other day
Duration
20-30 minutes
Target Depth
Deep soak to 4 inches
Transition to deeper, less frequent watering. This trains roots to grow deeper.
Week 4
Frequency
Every 2-3 days
Duration
30-45 minutes
Target Depth
Deep soak to 6 inches
Sod should be rooted. Begin moving toward a normal watering schedule. First light mowing when grass reaches 3-4 inches.
Do
- Water within 30 minutes of laying each section
- Check edges, corners, and areas near concrete — they dry fastest
- Water early morning (4-6 AM) to reduce evaporation
- Gently tug sod corners weekly to check root progress
- Keep all foot traffic off the lawn for 2 weeks minimum
- Wait 3-4 weeks for the first mow at the highest setting
- Apply starter fertiliser 4-6 weeks after installation
Do Not
- xWalk on new sod for the first 2 weeks
- xLet sod dry out — even one missed day can cause permanent damage
- xOver-water to the point of standing puddles or soggy soil
- xMow before roots have anchored (tug test must fail)
- xApply weed killer or heavy fertiliser for the first 60 days
- xLet pets use the new lawn until fully rooted
- xPark vehicles, place heavy objects, or host gatherings on new sod
Estimated Water Cost for the First 30 Days
New sod requires approximately 1 inch of water per day for the first week, tapering to 1 inch every 2-3 days by week 4. For a 3,000 sq ft lawn, this works out to roughly 1,800 gallons per day during peak watering. At an average water rate of $4-$8 per 1,000 gallons:
Frequently Asked Questions
How often should I water new sod?
Water new sod 3-4 times per day for the first 3 days, keeping the soil consistently moist to 1 inch depth. Reduce to 2-3 times daily for days 4-7, then once or twice daily in week 2, once daily in week 3, and every 2-3 days by week 4. The goal is to gradually train roots to grow deeper.
When can I mow new sod for the first time?
Wait at least 2-3 weeks before the first mow, or until the grass reaches 3-4 inches and the sod cannot be lifted when gently tugged. Set your mower to the highest setting and never remove more than one-third of the blade height. Use a sharp blade to avoid tearing the young grass.
How do I know if my new sod is getting enough water?
Lift a corner of sod — the soil beneath should be moist but not waterlogged. If the soil is dry or the sod feels light, increase watering. If water is pooling or the sod feels squishy, reduce watering. The edges and corners of the lawn dry fastest and need extra attention.
